SHIRT STUD.

Application filed September 2'?, 1921.

Tov all whomz't may @once/m.'

Be'v it known that I, JOHN W. SCHOELLNER, aI citizen of the United States, residing at Newark, in the county o-f Essex and State of New Jersey, have invented certain new and useful Improvements in Shirt Studs, of which thefollowing'is a specilication.

This invention relates generally to a method ofreinforcing metal parts and also to1an' article of jewelryin the forming of which the method is employed.

In the manufacture of an article of jewelry in the formlof'a removable stud or fastener for clothing, an elongated basememberv is made useof'which normally assumes a position with the stem and button portion of the devicev located substantially midway ben tween the extremities of the base member, provision being made for moving thel button, along the base' member to a point adjacent an end thereof' to facilitate the placing of the device in, or its remo-val from, a button-hole. InV order" to provide for the automatic centering of the button between the ends of thev elongated base member' aspring member is made use of f and' the-'base and base-engaging 4portions of the button take the form of hollow stems one of which enclosesl and' slides on the other, thespring beingenclosed. or housed withinl the hollow stems; This invention includ'esk a' method for forming. an improved reinforced" head' on" one` of the relatively minut'ehollow'stems in order toprovide for theforcing'of' the stem without collapse through a starclred and resistant button-hole and it'o correspondingly stiften and strengthen the entire base member. @ther features ofthe invention will be hereinafter referred to.

In the drawing,-

F igure lis a longitudinal section, partly' brokenaway of a fastening device containing an'v embodiment of the invention.

Figure 2 is a sectional view in' disassembled relation to the parts which are tol be formed into a reinforced" terminal member.

Figure 3 is a view similar to Figure 2 showing theparts assembled and subjected to onev stepin a` head-forming operation.

Figure 4; is a view similar to Figure 3 showing the parts subjected to another and final forming operation.

Serial No. 503,593;

Figure 5 is-an' endview looking atlthe interior of a conical terminal member shown in Figures 2 and 3.

Figure 6 is a side' elevation of a portion of a hollow stem before attaching the terminal member thereto.

Figure 7 is a cross-section of the hollow stem member shown in Figure 6" taken on the line 7`-7.

Referring to the drawing, ay shirt stud or fastener is shown in Figure 1 which includes the button memberor top 5, a hollow stem' 7" attached to the back of the topf member 5, and anV elongated basemember 9 whose function it is' toancho-r the device in the buttonhole` inu a wellkn'own" manner.

It will bewseen' that'the elongated base' member 9' extends substantially at right angles to the button stem 7lv and; that the but-tonl top 5, in thenormal position ofthe parts'shown in Figure 1, occupies a position substantially midway between the ends of the elongated base oranchoring member 9.

In order to move the button top, 5to a position adjacent' one end ofthe base 9, thel base member i'sfma-de-upv of a hollow stem member 11 which isimounted'to' slide' longitudinally in a? laterally diverted eXtension 13 oft-lie button stem 7; A helical spring 15 ofthe. expansion type' is: hel'd'in a compressed condition within" the/hollowV stem ll andbbearsat one end aga'inst'the' closed righthandendlr( of'thestem 11 in FigureV 1 and at'th 'e'otherendfagainst aseat 19 in the form of a` tongue of'metalcut'in the wall of the stem 13 and bent inwardly at an angle to theaxisofthe stemV to operate in a longitudinallyv extending-,slot 20 in the stem. It will thus. be' seen that the spring presses against the closed end'l? of the stem 1l and tends to press the stem 11 to the right, in Figure l, and against the tongue or seat 19 on the stern 13 thereby tending to press: the' stem 13 and button 5 to the left.

It will be seenthatthe button 5 and stem 7 can bemovedto the right along the stem 11V and against' the pressurev of the spring l5 until the button stem 7 'is stopped by engagement with astop lug 21 formed' at the upper right-hand extremity of the stem l1, to facilitate the passing of the right-hand end of the stem 11 through. the button-hole.

This operation is assisted by the angular or beveled formation of the stem-end 17, as will be clear.

In order to reinforce the opposite end of the stem 11 and also to make it possible to force this end through a button-hole closed and stiffened with starch, a pointed head or terminal member 23 is provided for the stem 11. The terminal member 23 also acts as a shoulder or stop which is engaged b-y the corresponding end of the stem 13 in the position shown in Figure 1 and which accordingly limits therelative movement of the stem 13 to the left.

The head or terminal member 23 is attached to they forked end of the stem 11 which is formed by the slot 2O in the following manner: A head core member 25, which may be spherical in form, is forced between the extremities ofthe separated portions or extensions 27 into which the slot 20 divides the stem, the stem extensions 27 being suitably anchored for the purpose. This operative step produces an upsetting or spreading of the extreme ends of the stem extensions, to form seats 29 fitted to the engaged contour of the core 25, as will be clear.

The next step in the operation consists in compressing the flaring end of the hollow conical head member 23 into encompassing and rigid engagement with the outer faces of the core-receiving seats 29 on the stem extension members to thereby bind the engaged parts into a rigid unitaryterminal member. The terminal thus provided for the longitudinally split end of the hollow stem is capable of penetrating a resisting buttonhole without collapse and at the same time acts as a rigid reinforcement for the split end of the tube as a whole.

It .will be clear that the two steps for forming the head can be provided in two separate operations or in successive stages of a single forming operation as may be found most convenient, and that by either process an exceedingly simple, eflicient. and readily formed reinforced terminal for the hollow stem is provided.

What is claimed is:

1. The method of forming aI terminal for an elongatedmember having spaced apart lateral walls which consists in forcing a terminal core member between the ends of said walls to spread the ends of the walls apart, and in' clamping a terminal shell about the core member and the spread-apart ends of the walls of the elongated member.

2. The method of forming a terminal for an elongated button anchoring member having a longitudinally divided end, which consists in bending the extreme ends of the divided portion outwardly away from each other by inwardly forcing a core member against said ends to form a seat, and in clamping a metal shell in enclosing relation to said core member and the outwardly bent extremities of the anchoring member.k

3. The method of forming a perforating terminal for a tubular member which consists in forcing a terminal core member against and into an end of the tubular member to spread apart the walls of the end of the tubular member to form a seat for the core, and in bending the flaring edge of a hollow substantially conical shell inwardly to grip the core member and spread apart endv of the tubular member. f

4. The method of forming a reinforced perforating terminal head for a longitudinally split tubular member, having spaced apart walls, which consists in forcing between the ends of the walls a core member having a greater width than the width of the space between the walls to thereby spread 1 apart the ends of the walls and form a seat for the core member, andv in bending the flaring edge of a conical shell into gripping relation with the spread apart ends of the walls of the tubular member and in enclosing relation to the core member.

5. The method of forming a reinforced perforating head for a tubular member having a longitudinally split end which consists in forcing a substantially spherical" core member against the end of the tubular member to force apart the walls and form a core-engaging seat, and in placing ahollow'conical shell in enclosingrelation to the core and compressing the flaring edge of the shell into locking engagement with the spread apart ends of the walls of the tubular member.

6. A fastener comprising a button having an elongated ,tubular base member, said base member being expanded at one end to form a seat, a terminal core member mounted on said seat, and a terminally pointed shell enclosing within its base said core member and the expanded end of the tubular base member. l

7 A fastener comprising a button having an elongated longitudinally divided base member, said button being movably mounted on said base member, the parts of said longitudinally divided base member being flared on one end to form a seat, a spherical terminal core member engaging said seat, and a hollow pointed shell enclosing within its base portion said core member and th flared end of the base member. f In testimony whereof I afiix my signature.
